BALPH J. SERPAS, OF KALAMAZOO, MIGEIGAN.

BEATER ENGINE.

Application filed April 4,

"citizen of the United States, residing at the city and county of Kalamazoo, btate of Michigan, have invented certain new and useful Improvements in Beater Engines, of which the following is a' specification.

This invention relates to improvements in beater engines. w

The main objects of this invention are First, to provide an improved beater engine lin which the beater roll is mounted upon fixed or non-adjustable bearings.

Second, to provide an improved beater engine in which the bedplates are yieldably and adjustably supported so that they may be adjusted to the work required and so that the machine is not likely to become clogged, and the neces'sity of care in introducing the stock is eliminated.

Third, to provide an improved beaterengine having these advantages which is very easily adjusted. i

Objects pertaining to details' and economies of construction 'and operation will definitely appear from the detailed description to follow. i w

I accomplish the objects of my invention by the devices and-means described in the following specification. The invention is clearly defined and pointed out in the .claims.

A structure which is a preferred embodiment'of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

F ig.` I is a plan view of a beater' engine embodying the features of my invention` Fig. II is a side elevation thereof.

Fig. III is a Vertical longitudinalj section. Fig. IV is a- Vertical lon 'tudinal section similar to that of Fig. I I of a slightly modified form or embodiment of my' inven- -ti'on.

In the drawing the sectional views are taken looking in the direction of the little- 1928. Serial No. 629,790.

the discharge end being consideraibly larger than the beater roll 6.

Between the beater rolls is a horizontal parti'tion or midrib 7 inclined in a direction opposite that lof the inclination of the in- 'lclined-bottom 2 of the tank. At its lower end the midrib 7' is provided With a dis-. charge opening 8 controlled by the gate 9, the pivot rod 10 of this gate being extended through the wall of the `'tank and having an ar'm 11 constituting a handle. When this valve is lifted the flow of stock down the midrib assists in opening it and holding it open.

In the embodiment illustrated I provide. two bedplates 12 for each beater roll, these sprinfrs. These nuts are provided` with bevelliad pinions 17, there bein several of the supporting arms for each dplate.

To snnultaneousl adj'ust these 'nuts I provide shafts18 ving pinions 19, the shafts being supported for rotative and axial movement in the bearings 20 on the bars 14 and being providedwith hand Wheels 21 by which t ey may be manipulated when in engagement and rotated, thereby adjust-l in the bedplates.`

oiled Springs 22 disposed between one of the bearin v20 and a collar 23 on the shaft holdthe pinions 19 in disengaged position.

For convenience in mani ulating the adjusting nuts of the lower be plates the structure described isslightly modified, the nuts 24 corresponding to the nuts' 16 being grooved to receive the yoke-like bracket 25 which carries the shaft 26 correspondingyto the shaft'- 18, and carrying the pinions 27 meshingwith the pinions 24, the pinions being int engagement at all times. verticall disposed adjusting shafts 28 are rovid having pinions 29 adapted to he rought into mesh with the pinion 30 on the Separate end of the shaft 26. The pinion 29 is normally disengaged by the coiled Springs' 31.

The shaft 28 are provided with hand Wheels 32. I thus provide a convenient means for adjusting the lowerbedplates, the adjusting means of which are normally below the level of the floor.

In the modification shown in Fig. IV the tank is provided with a top 33 and has a side door 34 through which the'stock may be' introduced. The discharge gate 4 lis operated with a rack and pinion mechanism but as the structural details of this mechanism form no part of this inven'tion, they are `'not herein described.

I have illustrated and described my ,improvement's in an embodiment which I have found very practical. I have not attempted to illustrate certain modifications or adaptations'which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to emhod .y or adapt the same as maybe desired.

ving thus described my invention what,

I claim as new and desire to seeure by Letters Patent is:
